Meter readings at home #allElectric #fossilFree
Meter readings and analysis of our electricity carbon footprint at home in 2026. The gas meter has gone: we are all-electric with a heat pump now!

|---|---|---|---|---|
| Month | Consumed kWh (/d) | Generated -kWh (/d) | Period | Notes |
| 2026-01 | 367 (11.8/d) | -66 (-2.1/d) | 20251231T17:53Z:02Z to 20260131T19:48Z (31d) | Meter readings: electricity generation 65.9kWh, export 0.6kWh, import 301.9kWh (thus net consumption (I+G-E) 367.2kWh, self consumption ((N-I)/N) 18%). See load profiles.
The Enphase emailed monthly report for January (triggered ) says: produced (generated) 66.1kWh (max 3.8kWh on the 24th), consumed 350.2kWh (max 18.8kWh on the 4th), grid energy imported 378.7kWh and exported 0.1kWh, grid dependence 86% (min 62% on the 31st). The Ecotricity energy bill for this month was a little under £110. (Last January was colder and the bill was ~£130 just for electricity.) Ecotricity's estimated annual consumption (ie imports) for us is now ~1.2MWh. For the month reported hph4 was 190kWh (heat 196kWh). Daikin stats report 208kWh for this month hph4 (possibly not including OpenTRV unit consumption). (Daikin since-installation figures reported : input space 801kWh, DHW 561kWh, total 1362kWh; output space 2196kWh, DHW 1294kWh, total 3490kWh; thus implied CoP: space 2.7, DHW 2.3, total 2.6. Pump running 2368h, space heating 1040h, DHW 276h. Eddi hph4 to end , with a few missing days from is 1286kWh so not far from Daikin 1362kWh.)
HDD12=197 vs 235 last January. |
